Mark Edwards is Professor of Early Christian Studies at University of Oxford. His publications include Catholicity and Heresy in the Early Church (Ashgate, 2009) and John Through the Centuries (Wiley-Blackwell, 2003).

"Throughout this useful volume, the repeated appearances of some of the same themes, issues and authors -- and, on occasion, the same texts -- in multiple chapters cumulatively invite the reader to appreciate the interconnectedness of diverse forms of literature and practice, and thus to ask whether the designation of them as 'diverse' would have been as obvious to readers and authors at the time. Perhaps more importantly, Edwards also warns against letting superficial similarities between texts become the basis for simple, reductionist statements about the 'religious identity' of authors, or seeking to neatly pigeonhole their works within clear intellectual genealogies. This detailed and thoughtful account is a useful introduction to a wide selection of early fourth-century writings and provides a fascinating insight into the innovation, experimentation and complexity of the age." -- Richard Flower , Late Antiquity

"Mark Edwards's remarkably rich book, at once a tour d'horizon and a tour de force, in many ways represents the distilled result of decades of patient work. It is written in crisp language, and its thirteen chapters are at once concise and sharp The great strength of Edwards's book lies with his sophisticated analysis of philosophical and patristic texts. The author's decision to read such philosophical polemics within the broader framework of religious history offers a new and enlightening perspective. He can thus highlight the emergence of new forms of saintliness (philosophical as well as Christian)."--Guy G. Stroumsa, Reading Religion

"In this rich study, Edwards offers a holistic picture of the age of Constantine, in which the religious, theological, and philosophical aspects stand out most conspicuously... this is a thorough, valuable, and enjoyable analysis, which will be in many ways an inspiration to scholars in ancient religions, early Christian studies, patristic theology, Roman history, and history of ancient philosophy." -- Ilaria L.E. Ramelli, Gnomon Vol. 90:1

"Edwards marshals an impressive array of sources from this period Recommended."--CHOICE
